the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
The surface diffusion of tungsten at very high temperatures
2014 The surface self-diffusion coefficient of tungsten in the region of extreme high temperatures (3 000-3 600 K) is determined from van der Mast experimental data on laser heated tips using our theory on tip evolution by capillarity forces and evaporation. In contrast to previous results at less high temperatures, the new results show a slope change in the Log Ds versus 1/T curve indicating a...

15 صفحه اولTungsten Behaviour at High Temperature and High Stress∗
Recently reported results on the behaviour of the tungsten under conditions expected in the Neutrino Factory target have strengthened the case for a solid target option for the Neutrino Factory. This paper gives a description of the measurements of the surface motion of tungsten wires, stressed by a pulsed current, using a Laser Doppler Vibrometer in order to measure tungsten properties at high...
